This separates `classPrivateMethods`'s dependency on
`classPrivateProperties`. It also starts a `PrivateName` at the hash
symbol, not the `Identifier`.
* Add support for class private methods
This commit adds parser support for the TC39 Stage 2 Private Methods
proposal.
This commit also changes "key" in ClassPrivateProperty from an
Identifier to a PrivateName, as well as disallowing #constructor as a
valid private field name.
* Add tests for string literal get/set/async
These should be treated as regular methods and not special get/set/async
behaviour.
* Add tests for class private methods
This also removes a test from the Test262 whitelist that failed before
the changes for private methods support and now passes.
* Modify class private prop tests for PrivateName
* Add class private prop tests for #constructor
* Fix existing ASI test case failure
Given that it refers to an identifier, it's somewhat confusing to have
to use .name.name to get the actual string. The type declared within
types.js is also incorrect, which this commit fixes.
* Arrow fns can't be used as the left side of a binary or ternary expression
Fixes#536
* Add test for logical expression with arrow function
* Fix eslint
* Distinguish between ternary's : and arrow fn's return type
* Correctly parse nested arrow functions inside conditional expressions
Defer the conversion of arrow function parameters to assignable nodes so that
it is possible to use the (invalid) ast to get the exact position of the (wrong)
arrow functions.
* Check params of arrow fns w/ type params or w/o return type
* Fix also async functions
* Add test from prettier
https://github.com/prettier/prettier/issues/2194
* Don't check arrow params if they are valid at the first attemp
* Use state instead of relying on the "noArrowParamsConversion" parameter
* Remove noArrowParamsConversion
Given that private fields can only be used within classes, any code
using them must be in a strict mode context. As private fields cannot
be deleted, throw an early SyntaxError.
* Add plugin for import.meta proposal
Fixes https://github.com/babel/babylon/issues/539
* Tests for assignment/mutation of import.meta
* Use correct identifier in failure message
* Simpler & more consistent script errors for import.meta
